If anyone has any objections, please let me know. ------------------ From: Takashi Iwai commit d6b340d7cb33c816ef4abe8143764ec5ab14a5cc upstream. The meddlesome gcc warns about the possible shortname string in trident driver code: sound/pci/trident/trident.c: In function ‘snd_trident_probe’: sound/pci/trident/trident.c:126:2: warning: ‘strcat’ accessing 17 or more bytes at offsets 36 and 20 may overlap 1 byte at offset 36 [-Wrestrict] strcat(card->shortname, card->driver); It happens since gcc calculates the possible string size from card->driver, but this can't be true since we did set the string just before that, and they are much shorter. For shutting it up, use the exactly same string set to card->driver for strcat() to card->shortname, too.
